I've been to Tiffany's many times before. It is local, convenient, and they have a large menu with pretty good food.
I was there this morning and we were a group of 8 who haven't seen each other in quite some time. After just a bit over an hour, we were asked to stop our conversations and leave the table as they needed it for other guests. Never before have I ever been asked to get up and leave even if we already finished eating.
So - if you want a very quick meal, this is the place to go, if you are looking to enjoy yourself, then I would choose somewhere else.
